No modifications to the ballast, it just has to be an electronic instant-start ballast. As long as it doesn't have EOL-protection any brand/model I've tested will do. Note.. the part where the tube starts out dim/pink isn't related to the ballast, thats because its old & low on mercury...occasionally you'll get one that happens to.

Yep same here, love seeing one EOL And yeah, this was one of the best 'shows' I've seen. Kinda doubt I'll bet another one that good. .lol.

In my case this was from an aquarium light (and I have plenty of spares) so I'll be sticking with fluorescent ... but yeah for general lighting, LED is a fine way to go these days!

Yep! Basically my reaction when I saw it do that.

Yep those certainly did good.. never would have lasted if I'd used brighter sets.. (also good thing I took them down, since part of that fence got thrashed down in a windstorm last month, probably would have broken bulbs and wires) It makes perfect sense with the ballast bulbs that as they get more hours on them they'll start failing more often .. and since twinkle bulbs tend to fail first, you've replaced some along the way, so they end up being various ages newer than the ballast. Yep, its all about perspective when seeing 2 sets near eachother. If you were to put a bright set next to them, it'd look really bright while the 2 dimmer sets wouldn't be as noticeable different. lol Of the 3 sets I had up, same thing, one of them was alittle brighter, and at night it looked bright. I even went out & looked at it after putting it up, thinking maybe multiple bulbs had burned out or something...

Sorry but can't read that, I only know english

@@XmasLightsGuy from what he is saying is Unnamed fluorescent lamp from this brand?

@@WolfDogFooxRoblox Thanks for the translation. Yep. no indication of brand or model anywhere on this one.

@@XmasLightsGuy oh I want to ask why does the first part of the dark end burns out? First like the second part doesn’t burn out.

@@WolfDogFooxRoblox Has something to do with how the filaments are, I'm really not sure the exact reason.

I still replace more twinkle bulbs than ballast, but I've noticed as my sets age, I'm replacing more ballast bulbs than I used to...I figure it'll eventually be roughly equal numbers. Those have done really well! Last November I put 3 sets along the backyard fence, and they ran 24/7 til atleast the end of February (purposely chose dimmer sets) I did replace some bulbs, but not allot. They did quite well considering running like that...

Pretty much so on a normal ballast. .lol. But I think these instant-start electronic ballasts don't allow it to rectify, they force AC power through ... they'll even light a tube with both filaments completely broken off their supports (ofcourse it won't last long before it fries)

Yep, an old piece of lumber really only does for testing. I've never seen a F48T12 slimline fixture in any store. .. .but if I ever wanted one, I could pretty easily convert a standard 2xF40T12 fixture to F48 slimline.

Yep. These were fairly common here at one point. Don't know if they're even made anymore though. I had this one on an aquarium for a number of years, til it went EOL.

Nice. especially if its an older one the GE's were good lamps.

Not quite sure what you said there, but this is a 15w lamp. (and running at somewhere between 19w to 22w with the overdrive)

Interesting.. the others I've had have been pretty similar color to this one.

@@XmasLightsGuy the colour is 7000K

@@SuperFusbass Very interesting. The KB's here are all 3000k

Yep, in nearly every one of these, the audio is removed during editing. (there's really nothing to hear anyway) .. I try to remember to put in the description if there's audio or not.

@@XmasLightsGuy I think it would be better if you had an external mic up close to the tube

@@coalthedergsune I don't think my camera has an input for external microphones. I could in theory record the audio separately(the basics of which are simple enough), and add it into the vid when editing, but its time-consuming & a fair bit more work - especially on videos that are split up into multiple short sections.

Thanks

This one only made some quiet little 'tink' sounds, with the background noise they really didn't get picked up by the camera.

Yep.

Houseplants & aquarium plants .lol. these are way too dim for any of those 'special' plants 🪴

I should try to do it more often. Sometimes I get busy .. and/or forget about that little pile of dead tubes I have waiting to be fried. .lol. I have one more recorded .. not sure when I'll get the chance to test/edit the video, but hopefully in the next few days.

Same here, as a kid I was fascinated with fluorescents, especially seeing one go EOL. I have a couple of the 6-foot slimline fixtures that I happened across at an estate sale. And yeah anything slimline shorter than that is rare, I've seen 4-foot fixtures before (and have a 4-foot lamp), I once a oddball length lamp in a vending machine (think it was 42-inch ) I'd personally like to have one of each size fixture from 2-foot up to 8-foot.

@@XmasLightsGuy yeah there certainly is (or used to be) oddball lengths of slimline and HO 800mA lamps made in addition to your run of the mill 2, 3, 4, 6 and 8 foot such as 42, 60, 64 and 84 inch lamps, which I would assume most if not all of these oddball sizes were used in outdoor signs, vending machines and similar niche fixtures and not general lighting. There are also F120T12, recessed Bi-pin, 10 foot tubes classified as sign lamps and the ballasts are rated in terms of total length rather than a range of wattages and T12, T8, T5 or a combination thereof, the way standard fluorescent ballasts are rated. Many years ago there were some very Interesting lamps produced to say the least. I have a 1991 Philips lighting catalog and there is an energy saving alternative to the F90T17, it is a F90T12, mogul bi-pin, 84 watts designed for use a F90T17 fixture, along with a F40T12- instant start medium bi-pin. I used to also have a 1993 GE catalog that got lost during a move last year 😡😥 and I remember seeing a F40T17 instant start mogul bi-pin, and I wanna say the F40T12- instant start as well if I remember correctly.

@@Sparky-ww5re I have some 18" HO lamps, plus a couple 3,4,5,6,7, & 8 foot. .. I believe they came in 6" increments. I did see one of the F120T12 once, weird-looking lamp - basically looked like someone took an 8-footer & a 2-footer and attached them together -- there was a clear connection spot at that point. And yep sign ballasts are like that, I have one, it says up to 6 lamps & a total length of...(don't remember the number) I've heard of those F84T17 energy savers. kinda funny because the F90T17 itself was an energy-saver version of the original F100T17. I have a couple of the F40T17 instant-start lamps, and one F40T12 too. Both were designed to run on a F48T12 slimline ballast.

Not quite sure what you said there since I only know english.. but something about tubular fluorescent lamps

He says “Burnt out tubular fluorescent lamp”

@@SuperFusbass Thanks for the translation.

I'm not sure of the the exact reason, but it has something to do with unstable flow of power in the lamp

I have a plasma globe, but none of those others. (would love to have a neon transformer) in the case of this lamp, the internal glass cracked & it lost vacuum

Oh.. I have plenty more. .LOL.

wow. But, yeah in rare cases the socket can melt, or the tube can crack at the bad end.. then it'll fall.(I've had them crack before, but not enough to fall out of the light.)

Yep.. sure did!

There really wouldn't have been much to hear... it made some little 'tink' sounds, but thats it. probably what you would have mostly heard was the pumps in the fishtank on the other side of the room since that was closer to the camera.

@@XmasLightsGuy I am see, very cool

Yep, that one is well used & nearing the end of its lifespan.

So true!

Never thought about it that way, but yeah does look kind of like cars/etc lined up on roads!

@Imakeelectronicchaos Yep that can happen! Its more likely with the modern sockets that can't take as much heat as the older ones like I used. I also shut this down & let things cool off every so often.

Yep.. that's pretty much it. .lol.

Nice! I have a couple of the 2-lamp version of those ballasts. Had thought about making a F8 fixture with one.

I know right, same

Oh yeah it sure did!

Yep thats the point when the tube lost vacuum.. Would have been interesting ti see what happened if it had held on longer. .lol.

@@XmasLightsGuy how did you made it loose vacuum

@@WeNeedSomeMusic Its just something that happens with these electronic ballasts. When there's that orange glow right in the end, its getting really hot - to the point where it'll melt the metal filament supports and/or internal glass around them.

@@XmasLightsGuy the magnetic ballast has the same but only the sides turns orange then like 10 seconds it started blinking non stop

@@WeNeedSomeMusic Yeah, I've seen orange end-glow happen for a brief period on magnetic a few times, and then just start flickering (in that case, rapid-start magnetic .. havent seen any on preheat/switch-start, they usually just start blinking)

Yeah, that was a cool find. Fairly uncommon to see a RS ballast for those small T5 lamps!

@@XmasLightsGuy I’ve got the single-lamp version in a DIY strip light that I made with my dad a while ago! I agree, they are so cool! Too bad there are no rapid start magnetic ballasts for the longer T5 lamps! Surprisingly, there wasn’t even a version for the F13T5 lamps!

@@rs12official I've never tried it, but the 2x version like I have here should be able to light a F13T5 or F14T5. It would be really cool if one did exist that was meant for a pair of F28T5 or even F54T5-HO lamps!

No they don't

@@jaedenspider877 おめー、塩対応だな😡

@rapidstart_12 LOL at "Home Dim ballast" !! I'm sure this is the only fixture with that particular ballast combination...

Yep these are nice stuff! I always liked that old large 'GE' etch.

@rapidstart_12 Its mostly just surface rust, overall not that bad. If I ever needed the fixture, a bit of sanding, some cleanup, & a paintjob .. then it'd be ready to go.

Yeah. I wasn't expecting that out of it! Think its pretty rare for one to go out like that. .lol.

I agree ,the last craziest eol I had with my fluorescent bulb was when the vacuum loss turn half of the bulb clear, your eol was the best eol I have ever seen, keep up with the good work 👏

@@Logan-pr5pv Clearing out half the phosphor .. wow that's a good one! I've never had more than a little at the end. I finished off another F20 recently, but it was nothing real special (other than there was a little 'light show' going on inside the bad end that was kinda cool). May put up the vid at some point later.

@XmasLightsGuy that,s good, thx for the heads up, btw the bulb eol I had with the half the phosphor blown was 2ft t8 but I am not sure about the brand the printing was faded. The bulb was almost nine years old, the fixture now a has a led bulb in it. I like watching your coll eol video btw. :)

@Casey Brown Same here. One of the best I've ever seen.
